In this paper, the executive of the 10th Five- Year Plan in the field of environmental protection and ecological constrution is reviewed, and the charactristics of economic growth and its environmental impact on the 11^th Five-Year Plan is forecasted and analyzed. A principal idea of eavironmental protection and ecological construction is put forward for the 11^th Five-Year Plan pertod: strensgthen the point treatment in key areas and set the main targets based on the idea. The relating countermeasures in national level are proposed as follows: set up appropriate ideas for official achievements by launching resources and environmental cost acconting; adjust the industrial struacture actively by industrial policies and strenuous work; develop circular economy, change the mode of environmental protecgon from end treatment to headstream and proeess control: strengthen the market mechanism in the process of pollution treatment, set up the system of "who treats who benefits" ; perfect interrelated laws and standards, strengthen the ability of environmental munagement; lay extra emphasis on two key targets: water pollution tretment in key river basins and management of the reserves; and combine the ecological consnuction and poverty alleviation in higher level. 展开更多

A decomposition model was applied to study the resource-saving and environment-friendly effects of air pollutant emissions(taking industrial SO2 emission as an example) in China.From the results,it is found that 38.93% and 61.07% are contributed to environment-friendly and resource-saving effects,respectively,by the dramatic decrease in industrial SO2 emission density(nearly 70% from 2001 to 2010).This indicates that China has achieved important progress during the 11th FYP(five-year plan) compared with the 10th FYP.A simultaneous equations model was also employed to analyze the influencing factors by using data from 30 provinces in China.The results imply that the influence of environmental regulation on environment-friendly effect is not obvious during the 10th FYP but obvious during the 11th FYP.Thus,the government should continue promoting the environment-friendly effect by further enhancing environmental regulation and strengthening the role of environmental management. 展开更多
